To all whom it m y concern:

Be it known that I, JACOB H. BoDrNeER, a citizen of the United States, and a resident of New. York, borough of Manhattan, in the county of New York and State of New York, have made and 'invented{certain new and useful Improvements in Water-Closet Bowls,

of which the following is a specification. I

My invention relates'to water closet bowls and has for its object to provide a-bowl so; constructed that should the' liquid seal for any cause become broken it will be immediately and automatically reestablished.

l/Vhere a number of closet bowls are con- I nected to a single waste pipe, as, for example,

in apartment houses, it has been found that occasionally the flushing of a bowl will-set up a vacuum within thewaste pipewhich will tend to break theliquid' seal of the various closet bowls connected to the drainage pipe and located below the particular bowl which has been flushed. In order to overcome this it has heretofore been proposed to provide an additionalvent, pipe-for each bowl and connect it to the waste pipe at a point above the main connection of the bowl to the waste pipe.- This, however, as will be readily appreciated, involves considerable expense. A further disadvantage to the closet bowl as heretofore constructed, has been caused by the evaporating of the water of the liquid seal when the bowl is not flushed over a considerable period of time, this evaporating of the water of the liquid seal allowing for the escapement of sewer gases. This escapement of the sewer gases may also occur where the gradual spilling'of the water of the liquid seal is caused by varying wind pressure down the vent pipe.

It is accordingly an object of my invention to provide a water closet bowl which is simple in construction and so designed and arranged that should the liquid seal for any cause whatever become broken a quantity of water will be automatically discharged into the bowl and the liquid seal accordingly reestablished.

A further object is to accomplish the aforementioned ends in a simple and practical manner, and to provide a bowl which willremain in a clean and sanitary condition, and with the foregoing and other objects in view, my invention consists in the improved water closet bowl illustrated in the accompanying drawing and hereinafter described and claimed, and in such variations and modifications thereof, as willbe obviousto;

those skilled in the tion relates. W. In the accompanying drawing: Figure 1 is top .plan view of .my im art to'which my invenjproved CIOSQt bOVVI, agportion thereof being broken away and illustrated in section;

Figure 2'is a viewin vertical section taken onthe line 2 20f Figurel; and i l Figure 3 is a detail View in section taken on the line -3'-3,of Figure 2.

Referrin'gispecificallyto theseveral views, 1 wherein similar reference i'iumeralsdesignate corresponding ".parts throughout, my' improved closet bowl is formed with" the usual body 10, having a downwardlyproject ing trap wall 11 1.vhichgextejnds below the upper'rim of the usual basinportion'12, so

that-When the basin, portion. is filledwit'h" watera'jl iquid seal13.will!bemaintained betweenth'e vent or soil p pe-l leand the per open extremity,'otthe' bowl.v

ing into the body of the bowl and. is adapted to flush the same in the usual manner. Car

ried by the bowl 10, and preferably formed integrally with the same, is an auxiliary compartment 15, the same communicating with the bowl below thetop surface of the liquid seal through, the restricted opening 16 and with the bowl at a considerable dis tance above the top of the liquid seal,

through the air vent 17. The auxiliary com- I partment 15 is formed with the sidewalls 18 and top wall 19, all of which are preferably formed integrally with the bowl proper,

so as to resent a neat and leasin a earance, and at the same time provide for a rigid, strong and economical construction. A float valve 20 is located within the auxiliary compartment 15 and hasthe float 21 carried on the extremity of the valve rod 22, the latter, as more clearly shown in Figure 3, carrying the valve proper 24, which is adapted to close against the seat 25. An auxiliary flush pipe 26 leads from the float valve 20 directly into the flush tank 14; it being noted in this regard th'at'the float valve is accordingly adapted to opof the tank. The float valve'is so. arranged that should the water within the basin 12 for any cause fall-below the level at which it should be maintained for a proper liquid erate independently of the main flush valveinto the auxiliary compartment and from thence into the'bowl proper, whereupon the liquid seal will again be established and maintained at its properudepth or height.

From the foregoingit will be observed that should the flushing of a closetbowl emptying into the same soil pipe as my improved bowl set up at-vacuum and thus cause a siphoning of the liquid seal the float valve will immediately operate and discharge water into the bowl so as to reestablish the liquid seal thereof. Further, should the bowl be left for a considerable time without flushing there will be no danger of escapem'entof sewer gases ordinarily caused by theevaporation-of the water of the liquid *seal, as with' myv improved bowl any evaporation of the water of the liquid seal will be immediately compensated for by fa'n'ew quantity of water being discharged into the auxiliary-compartment and then into the bowlprop'er.-

"For the same reason,- any spillin of the water of the liquid seal,- such-as may be caused by windpressure down the ventpipe, will be immediately compensated forand the liquid seal reestablished; The auxiliary compartment will at all times be maintained-in'a clean-ands'a'nitary condition, as each time the bow-l is flushedthe level of the liquid seal will belowered, causing 'a corresponding flushing of the auxiliary compartment.

Having thus described and'explained my invention, 1 claim and desire to secure by Letters Patent :-A- closet-bowl corn-prising a body portion having a downwardly extending trap wall,

an;- auxiliary compartment protruding from' the body portion of the bowl and formed integrally ther'ewitlr, said auxiliary c0mpartment being substantially vertical and adapted to house an automatic float valve. thei'ein an air vent communicating with the body portion of the bowl and said auxiliary compartment above the highest level of liquid within'the bowl, a liquid outlet com municating with the auxiliary compartment and with" said bowl below the level offthe bottom of said trap wall, a water inlet supcommunicating with the auxiliary compartment, and an automatic float shut-off valve located within said auxiliary compartment controlling' said water inlet andadapted to automatically maintain liquid at a predetermined height in the liquid seal of the bowl. v Signed at New York, borough of Manhattan, in the county of -New York-and State of" New :York, this 10th day or August, A.
